If you are looking for additional trading limits to trade in FnO, certain brokerages allow pledging of equity shares to get additional trading limits in FnO.

ICICI and Sharekhan has this option. I have tried both. Sharekhan seems to charge 16% pa as they seem to consider this limit as delay payment.

Go for ICICI which offers this for free ! In ICICI , go to FnO tab and use "Shares as Margin" link to do this.

Does any other broker give this feature. Pls share !
